One of Buffett's most famous quotes: You can't make a good deal with a bad person. The meaning is that if a company's management is bad, don't do business with that company or its leaders, and definitely don't invest in it. Everyone knows this, but it's not easy to follow. For example, in the past few days, $BTC and $ETH have skyrocketed, and many people are getting excited again. I won't trade, though. All the so-called 'leaders' and 'management' of crypto projects—none of them are good people. Yes, none of them. Is ETH's Vitalik and the foundation team good people? As for $BTC, it's a bit controversial. Many people think it's ownerless. But are the people managing $BTC, or those with the funds to influence $BTC, good people? These people are no different from those running scam operations. Some are blatantly aggressive, while others just disguise it better.
